Answer:

x = 6

Step-by-step explanation:

$\blue\textsf{\textbf{\underline{\underline{Question:-}}}}$

Write an equation in point-slope form for the line that has a slope of $\bold{\dfrac{1}{5} }$ and contains the point (2, -9).

$\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

$\sf{Formula\:for\:Point-Slope:-}$

$\dashrightarrow\bigstar\star\boxed{\bold{y-y_1=m(x-x_1)}}\star\bigstar\dashleftarrow$

Where

y₁ = the y-coordinate of the point that the line contains

m = slope

x₁ = the x-coordinate of the point that the line contains

Provided Information:-

y₁ = -9

m = $\dfrac{1}{5}$

x₁ = 2

Substitute the values:-

$\sf{y-(-9)=\dfrac{1}{5} (x-2)}$

On simplification,

$\sf{y+9=\dfrac{1}{5}(x-2)}$

According to the answer and explanation, we conclude that

[<u>The correct answer is Option B]</u>

In 2013, the population of China was estimated to be 1,360,760,100. Round off the number of people

Aleksandr [31]

Answer:

a) 1,360,760,000

b) 1,361,000,000

c) 1,400,000,000

d) 1,360,800,000

Step-by-step explanation:

We have to round off the given population number to certain digits.

The following are the rules to round of a number:

First identify the digit to be rounded.
If this digit is followed by 5,6,7,8,9 then we round up the number that is increase the digit by 1 and all the numbers to right becomes zero.
If this digit is followed by 0,1,2,3,4 then we round down the number that is decrease the digit by 1 and all the numbers to right becomes zero.

a) to the nearest thousand.

Thousands place: 0

Right Digit: 1

We round down the number

Rounded to the nearest 1,000 or t he thousands Place = 1,360,760,000

b) to the nearest million

Millions place: 0

Right Digit: 7

We round up the number

Rounded to the nearest million places = 1,361,000,000

c) to nearest hundred million

Hundred million place: 3

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,400,000,000

d) to the nearest hundred thousand.

hundred thousand place: 7

Right Digit: 6

We round up the number

Rounded to the nearest million places = 1,360,800,000
